It's not the check-up spaniel. That spaniel stands up on two legs, not fuzzy tail.
Can you post a picture of your dog? Did you say the head moves or does not move?
There aren't many like the one that you describe- ball bearing chest, fuzzy tail. It's either one of the following, or it's a custom (or even more unlikely, a prototype):
Fearless Friends shepherd
Twinkling Sled husky

And the spaniel... maybe the Care Center pup, if yours stands up on two legs... I need to do some more research.
... okay, I think you have the spaniel from "Take Care Pup".
